Preface
Purpose
Audience
This book covers the basics of Teradata database administration, giving you the essential tasks and the procedures for doing them. Chapters in this book are either designed for all DBAs or split tasks into two major groupings indicated in the chapter title: those for application DBAs, who are concerned with the design and performance of queries, and administrative DBAs, who are responsible for the day-to-day operation and maintenance of the data warehouse.
This book provides more details on topics of interest primarily to database administrators.
Where complete syntax is necessary or in-depth details are required, this book may point you to other books with more extensive information.
This book is intended for database administrators (DBAs). It is also useful for system operators.
